The co-stars joined about 60 others at Brenda & Ken of Wolfied Pub after having a private dinner at Donatellos Restaurant in Indiana, Penn.

“The owner of Donatellos bought them all a round of shots when they first walked in the door to get the party started. Rachel and Jake, along with the director and crew, were on the dance floor and mixing it up,” a source told the mag.

When the dance floor got too crowded, Jake and Rachel moved into a corner booth for privacy before leaving together around 2am.
